Hi,
So i think u are a self learner, like i did few years back. That time pinnacle was a gud compiler now a days theres keil and many others to add with. your problem will be compiling the assembly routines then try to download Keil compiler from Keil.com a trial version. You can start with their example programs and learn the syntax and other things there it self.

All the Best to u
